Tidal power generation cable

The utility model discloses a tidal power generation cable. The service life of the cable is shortened to solve the problems that the cable is easy to impact and corrode when running in a seawater environment for a long time. According to the utility model, the plurality of cable conductors are arranged in parallel around the axis of the armor layer, the insulating layers wrap the cable conductors, the outer sides of the insulating layers are in mutual contact, the waterproof layer wraps the insulating layers outside the cable conductors, the armor layer wraps the waterproof layer, and the filling layer is arranged between the water blocking layer and the insulating layers, so that the structure is more stable; the insulating layer prevents electric leakage, the filling layer improves the anti-impact recovery capability of the cable, the waterproof layer prevents water leakage, and the armor layer improves the anti-impact performance and the anti-corrosion capability of the cable, so that the service life of
